To find the value of a variable you must know the basics of pre-Algebra.


Example:


2x+9=39


To find he answer of this you must subtract 9 from both sides

Then you are left with…


2x=30

Since 2x=30 means 2 times x equals 30

You can divide 2 from both sides to find the answer

Which is…

x=15

The complex number _______ lies in the shaded area of the graph. The complex number _______ does not lie in the shaded area.
Anastaziya [24]
Think of imaginary numbers on a complex plane as coordinates - take the real part, that's the x coordinate, the imaginary part that's the y coordinate.

Therefore, for the first blank, -1+3i lies in the shaded area, because its coordinates are (-1,3).
And following on from that for the second one, -4i does not lie in the shaded area, since its coordinates are (0,-4).

Tl;dr is taking a complex number a+bi and placing it on a complex plane, it will have coordinates (a,b)
